hello everyone ,i need help with lis3dsh power waste

when i use lis3dsh , i test the power waste is 1.7mA, is more big than the discription in datasheet. 

the way i use it: the circuit board use STM32F4discovery , i init the gpio ,and then measure the Electric current.

when i measure the 

Electric current i haven't init the reg of lis3dsh .

question:1)How much is the lis3dsh current

2）How to configure lis3dsh to get it into low power

Please read carefully the

http://www.st.com/content/ccc/resource/technical/document/datasheet/23/c3/ea/bf/8f/d9/41/df/DM00040962.pdf/files/DM00040962.pdf/jcr:content/translations/en.DM00040962.pdf

.

The current consumption in power-down mode is 2uA and the sensor without any initialization is in power-down mode.

I suppose that you measure the current consumption incorrectly.
